A Bump on the Anus: Haemorrhoid, Skin Tag, Abscess or Wart

Noticing a bump on the anus can be alarming, but many causes are benign. Understanding the differences between haemorrhoids, skin tags, abscesses and warts helps you decide when to seek medical advice and how to manage symptoms comfortably.

Common Causes of a Bump on the Anus

1. Haemorrhoid
2. Anal skin tag
3. Anal abscess
4. Anal wart

Below, we explore each possibility in turn—how to spot them, what might help, and when to speak to a doctor.

1. Haemorrhoids

Haemorrhoids (piles) are swollen blood vessels in or around the anus. They’re very common, affecting around half of adults by age 50.

Key Features

• Location: Inside (internal) or under the skin around the anus (external).
• Appearance:
  • Internal haemorrhoids are not visible unless they prolapse (stick out).
  • External haemorrhoids look like small, bluish lumps.
• Symptoms:
  • Itching or irritation
  • Pain or discomfort, especially when sitting
  • Bleeding bright red blood during bowel movements
  • A lump you can feel or see

What Triggers Haemorrhoids?

• Straining during bowel movements
• Chronic constipation or diarrhoea
• Sitting for long periods
• Pregnancy and childbirth
• Being overweight

Management

• Home care:
  • Warm sitz baths (10–15 minutes, 2–3 times/day)
  • High-fibre diet and plenty of fluids to soften stools
  • Over-the-counter creams or suppositories containing hydrocortisone or witch hazel
• When to see a doctor:
  • Heavy or ongoing bleeding
  • Pain that doesn’t improve with home treatment
  • A large, painful lump that won’t reduce

2. Anal Skin Tags

Anal skin tags are small, soft flaps of skin that hang around the anus. They’re harmless but can cause self-consciousness or mild irritation.

Key Features

• Appearance: Flesh-coloured or slightly darker, soft, and painless.
• Size: Usually a few millimetres to a centimetre.
• Symptoms:
  • No bleeding
  • Little to no pain
  • Occasional itching if irritated by wiping

Common Causes

• Result from healed external haemorrhoids
• Skin stretching or minor tears (fissures)
• Genetics (some people form tags more easily)

Management

• Home care:
  • Gentle wiping; use moist toilet wipes without alcohol
  • Loose-fitting cotton underwear
• Medical options (if bothersome):
  • Simple removal under local anaesthetic
  • Cryotherapy (freezing) or cauterisation

3. Anal Abscess

An anal abscess is an infection in the anal glands, resulting in a painful collection of pus. It requires prompt medical attention.

Key Features

• Appearance: Red, swollen, painful lump near the anus.
• Symptoms:
  • Severe throbbing pain, worsens when sitting
  • Fever, chills or general discomfort
  • Possible pus drainage with foul smell
• Risk factors:
  • Poor hygiene
  • Underlying conditions like Crohn’s disease or diabetes

Why It Matters

Left untreated, an abscess can spread infection or form a chronic fistula (an abnormal channel between the anus and skin).

Management

• Urgent care:
  • Do not try to squeeze or lance it yourself
  • Seek medical review—drainage under anaesthetic is usually required
• Aftercare:
  • Antibiotics if prescribed
  • Warm sitz baths to promote healing
  • Pain relief (e.g., paracetamol or ibuprofen)

4. Anal Warts

Anal warts (condylomata acuminata) are caused by certain strains of human papillomavirus (HPV). They’re contagious and may recur.

Key Features

• Appearance: Flesh-coloured or grey bumps, often in clusters resembling cauliflower.
• Symptoms:
  • Itching or discomfort
  • Possible bleeding on friction
  • Sometimes no symptoms at all

How You Get Them

• Skin-to-skin contact during sexual activity with an infected partner
• Rarely from non-sexual contact with contaminated surfaces

Management

• Medical treatments:
  • Topical prescription medications (podophyllotoxin, imiquimod)
  • Cryotherapy (freezing off warts)
  • Surgical removal or laser therapy for large clusters
• Follow up:
  • Regular check-ups, since warts can come back
  • Consider HPV vaccination if not already immunised
